The GE90 Growth, which includes the GE90-110B and GE90-115B versions, is one of the largest and most powerful engines in the world. Developed exclusively for the current models of the Boeing 777 family—the 777-200LR (Long Range), the 777-300ER (Extended Range), and the 777-200F (Freighter)—these engines are characterized by a thrust of up to 115,000 pounds.
